The Expedition
• In 1804, the Corps of
Discovery left the Mississippi
River at St. Louis.
• They travelled down the
Missouri River as far as they
could go.
• Half way down the Missouri
River, Lewis and Clark hired a
fur-trader named Toussaint
Charbonneau.
• His wife, Sacagawea was very
helpful to the Corps, because
as a Shoshone, she knew how
to translate for some of the
Native American tribes that
Lewis and Clark encountered.
Sacagawea
The Expedition
• Once they got to Great Falls
the Missouri River turned
South.
• The expedition struggled to
find a pass through the
Rocky mountains when they
reached the Continental
Divide.
• After splitting up Lewis and
Clark both arrived at the
Pacific Ocean in the Oregon
Territory.
Outcome of the Expedition
• While exploring, the Corp of Discovery did
not find a water route to Pacific Ocean, nor did
they blaze a path for future settlers.
• They did bring back important maps of the
regions they explored, information about
plants and animals that lived west of the
Mississippi River and established peaceful
relationships with some of the Native
American tribes that they met.
